I love this very dark brown colour. It goes opaque with two carefully applied coats. It's dark enough that it may appear black in dim lighting but you can easily see the brown tinge in good light.

As for formula, it does result in tipwear quickly. I use Seche Vite topcoat over the top and it still chips and wears near the edges fairly soon. Still, I like the polish. I'm not sure if this brand is still available at Sephora as they've now partnered with OPI for their polishes.
